Clarification of the status of Paraferreola Šustera, 1912 as an available genus name in Pompilidae, and the identity of Sphex ursus Fabricius, 1793 in Mutillidae (Hymenoptera)

The usage of Paraferreola Šustera, 1912 since its proposal as a genus spider wasps, but based on misidentified type species ( Sphex ursus Fabricius, 1793, actually Mutillidae), shows that it continues to be applied (although infrequently) in Pompilidae, despite the new names Eoferreola Arnold, 1935 and Tea Pate, 1946) for equivalent generic concept. Application Article 70.3.2 fourth edition International Code Zoological Nomenclature permits correction erroneous designation originally intended rhombica Christ, 1791), thus maintenance valid Pompilidae. Examination holotype specimen has shown senior synonym Mutilla vesta Cresson, 1865 junior synonyms, which name must Dasymutilla (Fabricius, 1793), comb. nov.
